My pc (hp500-277c) was acting funky last night. Wasn't showing I had audio cords plugged in. So since I didn't have much on it, I factory reset it. Come this morning I go to log on and I got a black screen. I've successfully factory reset it 3 times prior to this. I have/had Windows 8.1 on the partition for it. But now it seems my Windows portion of my pc was deleted now. My recovery options from the startup menu will not show up now either. Now when I start it, I get a dialog box saying Windows wasn't installed correctly and to restart with 'Ok. It will loop the same problem when I press ok. I've received top quality help from this site before and was hoping somebody could shed some light on my situation.
